Shiva Purana
त्रिपादं मंत्रजाप्याच्च पूजया पूर्णभक्तिमान् । शिवलिंगं च भक्तं च पूज्य मोक्षं लभेन्नरः ११६ ।
Three-fourths can be achieved by the recital of mantras and a man be comes full-fledged devotee by means of worship. A man who worships both the phallic emblem of Śiva and the devotees of Śiva attains salvation.
